Description

Die Erfindung bezieht sich auf eine kombinierte Klebe- und Formschlußver­ bindung zweier Bauteile, wie sie beispielsweise in der DE 38 11 427 C2 ge­ zeigt ist. Dort wird eine Verbindungsanordnung von Karosserieteilen von Kraftfahrzeugen beschrieben, wobei im Bereich der zu verbindenden Karos­ serieteile eine Einspritzöffnung vorgesehen ist, in die nach dem Zusammen­ setzen und gegeneinander Fixieren der Karosserieteile ein aushärtbarer, pastöser Klebstoff unter Bildung einer Klebeverbindung einpreßbar ist. Die ergänzende Formschlußverbindung wird zum einen durch aufeinander ab­ gestimmte Formgebungen der Karosserieteile und zum anderen beispiels­ weise durch zusätzliche Fixiernieten bewirkt.The invention relates to a combined adhesive and positive locking Binding two components, such as ge in DE 38 11 427 C2 shows is. There is a connection arrangement of body parts from Motor vehicles described, being in the area of the checks to be connected series parts an injection opening is provided, after which together place and fix the body parts against each other a curable, pasty adhesive can be pressed in to form an adhesive connection. The complementary form-locking connection is on the one hand by on each other coordinated shapes of the body parts and, for example caused by additional fixing rivets.

Es ist die Aufgabe der Erfindung eine weitere Variante einer kombinierten Klebe- und Formschlußverbindung für zwei Bauteile aufzuzeigen, die weiter­ führende Anwendungsmöglichkeiten bietet.It is the object of the invention a further variant of a combined Show adhesive and positive connection for two components that continue offers leading applications.

Die erfindungsgemäße Lösung ist im Kennzeichen des Patentanspruches 1 zu sehen. Eine besonders vorteilhafte Verwendungsmöglichkeit ist mit Pa­ tentanspruch 4 aufgezeigt.The solution according to the invention is in the characterizing part of patent claim 1 to see. A particularly advantageous use is with Pa claim 4 shown.

Bei einem mit einem Airbag ausgestatteten Lenkrad eines Kraftfahrzeuges ist der Airbag in der Regel in der Lenkradnabe untergebracht. Deren Ab­ deckkappe weist an geeigneter Stelle eine Sollbruchlinie auf, so daß der Airbag austreten und sich entfalten kann. Der dabei schlagartig weg bewegte Teil der Nabenabdeckung schlägt ggf. mit großer Wucht auf den Lenkrad­ kranz. Ist die besagte Abdeckung mit weiteren aufgesetzten Elementen, z. B. Zierringen oder dergleichen, ausgestattet, so sollten sich diese bei dem be­ schriebenen Vorgang nicht von der Nabenabdeckung lösen. Dies setzt eine absolut sichere Verbindung voraus. Die erfindungsgemäße kombinierte Klebe- und Formschlußverbindung eignet sich hier in besonderer Weise.In a steering wheel of a motor vehicle equipped with an airbag the airbag is usually housed in the steering wheel hub. Their Ab Cover cap has a predetermined breaking line at a suitable point, so that the Airbag can escape and unfold. That suddenly moved away Part of the hub cover may hit the steering wheel with great force wreath. Is said cover with other patch elements such. B. Ornamental rings or the like, they should be at the be Do not remove the written procedure from the hub cover. This sets one absolutely secure connection ahead. The combined according to the invention Adhesive and positive connection is particularly suitable here.

Die Erfindung ist nachstehend anhand eines Ausführungsbeispieles be­ schrieben und in der zugehörigen Zeichnung dargestellt. Dabei zeigtThe invention is based on an embodiment wrote and shown in the accompanying drawing. It shows

Fig. 3 das aufgesetzte Bauteil (Zierring) in seiner Ausgangsform vor der Montage. Fig. 3 shows the attached component (decorative ring) in its initial form before assembly.

Gemäß Fig. 1 weist ein Lenkrad 1 einen Lenkradkranz 2, Speichen 3 sowie eine Lenkradnabe 4 auf. Hinter einer Abdeckkappe 5 der Lenkradnabe 4 ist eine Airbageinheit (hier nicht gezeigt) untergebracht. Damit der Airbag sich im Auslösefall relativ ungehindert in den Fahrgastraum hineinbewegen (aus der Zeichenebene heraus) kann, ist die Abdeckkappe 5 nahe eines auf sie aufgesetzten Zierringes 6 mit einer zumindest teilweise den Zierring 6 umge­ benden Aufreißnaht 7 ausgestattet (vgl. Fig. 2). Der Zierring 6 wiederum umgibt eine zentrisch auf der Lenkradnabe 4 angeordnete Zierscheibe 8, die beispielsweise ein Firmenemblem 9 enthalten kann.Referring to FIG. 1, a steering wheel 1 to a steering wheel rim 2, spokes 3, and a steering wheel hub 4. An airbag unit (not shown here) is accommodated behind a cover cap 5 of the steering wheel hub 4 . So that the airbag can move relatively freely into the passenger compartment (out of the plane of the drawing) in the event of deployment, the cover cap 5 near an ornamental ring 6 placed on it is equipped with an at least partially tearing seam 7 surrounding the ornamental ring 6 (see FIG. 2). . The decorative ring 6 in turn surrounds a decorative disc 8 which is arranged centrally on the steering wheel hub 4 and which can contain a company emblem 9 , for example.

Damit bei der explosionsartigen Entfaltung des Airbag und der damit einher­ gehenden schlagartigen Schwenkbewegung eines innerhalb der Aufreißnaht 7 angeordneten Bereiches 5.1 der Abdeckkappe 5, welcher dann ggf. auf den Lenkradkranz 2 aufschlägt, ein Ablösen des Zierringes 6 verhindert werden kann, ist die in Fig. 2 dargestellte kombinierte Klebe- und Form­ schlußverbindung vorgesehen.In order for the decorative ring 6 to be prevented from detaching during the explosive deployment of the airbag and the associated sudden swiveling movement of an area 5.1 of the covering cap 5 which is arranged within the tear seam 7 and which then optionally strikes the steering wheel rim 2 , this is shown in FIG. 2 shown combined adhesive and positive connection provided.

Hierbei weist der Zierring 6 über den Umfang verteilt (vgl. Fig. 3) vier La­ schenpaare auf, wobei jeweils eine innenseitige Lasche 10 mit einer Durch­ brechung 11 ausgestattet ist, der ein schmales Laschenende 12 einer außenseitigen Lasche 13 zugeordnet ist. Für die Montage des Zierringes 6 auf den inneren Bereich 5.1 der Abdeckkappe 5 ist diese an den entspre­ chenden Stellen für den Durchtritt von innenseitigen und außenseitigen La­ schen 10,13 mit entsprechenden Ausnehmungen 14,15 versehen. Here, the decorative ring 6 distributed over the circumference (see. Fig. 3) four pairs of loops, each having an inside tab 10 is equipped with an opening 11, which is associated with a narrow tab end 12 of an outside tab 13 . For the assembly of the decorative ring 6 on the inner region 5.1 of the cover cap 5 , this is provided at the corresponding points for the passage of inside and outside tabs 10 , 13 with corresponding recesses 14 , 15 .

Wie insbesondere Fig. 2 zeigt durchgreift das schmale Laschenende 12 in montiertem Zustand des Zierringes 6 die Durchbrechung 11 und ist an der Abdeckkappenrückseite 16 entsprechend zurückgebogen, so daß eine sta­ bile, einen Teil des inneren Abdeckkappenbereiches 5.1 vollständig einfas­ sende Formschlußverbindung entstanden ist.As especially FIG. 2 passes through the narrow tab end 12 in the mounted state of the trim ring 6 the opening 11 and is bent back according to the Abdeckkappenrückseite 16 so that a sta bile, a part of the inner Abdeckkappenbereiches 5.1 completely einfas send form-locking connection is formed.

Vorteilhafterweise ist über den gesamten Umfang des Zierringes 6 zwischen die einander zugewandten Flächen von Zierring 6 und Abdeckkappenbe­ reich 5.1 ein doppelseitiges Klebeband 17 eingesetzt, wodurch sich eine zusätzliche Klebeverbindung ergibt. Das Klebeband 17 ist vorzugsweise als Schaumstoff-Klebeband mit Druck-Feder-Kennlinie ausgeführt, so daß Maßtoleranzen überbrückt werden können. Außerdem kann dadurch bei ho­ hem örtlichen Druck (z. B. "Nothupen") ein Einbeulen des Zierringes 6 ver­ hindert werden. Anstatt eines doppelseitigen Klebebandes 17 könnte natür­ lich auch eine aufzustreichende viskose Klebemasse eingebracht sein. Die Funktion dieser zusätzlichen Klebeverbindung ist es jedenfalls unter ande­ rem, bei der im Auslösefall des Airbag sich mehr oder weniger zwangsläufig ergebenden Relativbewegung zwischen innerem Abdeckkappenbereich 5.1 und Zierring 6 zusätzlich stabilisierend zu wirken und z. B. Scherkräfte auf­ zunehmen.Advantageously, a double-sided adhesive tape 17 is used over the entire circumference of the decorative ring 6 between the facing surfaces of the decorative ring 6 and cover cap 5.1 , which results in an additional adhesive connection. The adhesive tape 17 is preferably designed as a foam adhesive tape with a compression spring characteristic so that dimensional tolerances can be bridged. In addition, this can prevent ver bulging of the decorative ring 6 at high hem local pressure (eg "emergency horns"). Instead of a double-sided adhesive tape 17 , a viscous adhesive to be spread could of course also be introduced. The function of this additional adhesive connection is in any case, among other things, to additionally have a stabilizing effect in the event of the airbag being triggered, more or less inevitably resulting relative movement between the inner cap region 5.1 and the decorative ring 6 and z. B. Shear forces increase.
